METHOD OF TURNING CASKS, 85C., FROM SOLID PIECES.

Specification of Letters Patent No. 11,136, dated June 20, 1854.

To all whom t may concern Be it known that I, JAMES I. OsBoRN, of the village of Staunton, in the county of Hunterdon, State of New Jersey, have invented a new and useful Improvement in Making Barrels, Casks, Tubs, &c.

The nature of my improvement consists m cutting the bodies of barrels out of blocks of wood, without injuring the cores, by

means of longitudinal knives, connected with cross-heads, and fed by screws.

To enable others, skilled in the art, to make and use my invention, I will lproceed to describe its construction and operation, reference being had to the annexed drawings forming part of this specication, in which- Figure 1 is a top view of my machine. Fig. 2, a bottom view. Figs. 3 and 11 views of side and cross-heads.

Similar letters refer to like parts.

A is the frame; B B', spindle; C C', carriers; D D, longitudinal tool-bearers; E E,

y cross-heads; F F", guide-rests; G G, guidepieces; H, set-screws; I, feed-screws; LL, bearer; M, jamfnut; N, jam-nut; O, jamnut; P, bearer; Q, groove;` R, connectingrods; S, bearer; T, gear-wheels; U, pinion; W, slide; K, am-nut, Y, bearing-pins.

The feed-screws, I, being connected with the gear-wheels T, revolve with them, and,

consequently, give a longitudinal motion to' the cross-heads, E E. The gear-wheels T, give motion to the pinion, U, to which the spindle, B, is attached.` One end of the knife, D, rests in the slide WV. This slide runs in the groove Q. The slide IV is attached to the cross-pieces G which are regulated by the set-screws H. The other end of the tool-bearer, D, passes through the guide-rest F. The block out of which the barrel, Cask or tub is to be turned, is sustained by the carriers` C C, which are screwed up or relievedby means of the nuts K, M, N, O.

Motion being communicated to the gearwheels T, the cross-head E is carried for ward, and the cutter on the opposite end of the tool-bearer D enters the end of the block and cuts in as i'ast as fed by the screws I. The cross-head, E, is connected with another cross-head, E, on the opposite end of the machine, by. means of the connecting-rods R. The tool-bearer, D, cuts to the center of the block, when the motion of the gearwheels is reversed, and the knife withdraws.

i at one operation.

On reversing the motion of the feedscrews I, the cross-piece E is carried in an opposite direction, so that the tool-bearer D ente-rs and cuts upon the end of the block opposite to that which has already been out,

and in the meanwhile the tool-bearer D is' being withdrawn from the cavity it has already turned. The guide-rests F F, it will be observed, are divided by oval-shaped separations. This particular form 'is given, so that the tool-bearers may cut out barrels having bulges.

In the large machine it intended that the tool-bearers shall be placed between every other one of these separations, on the guide-rests, in order that as many different barrels may beturned from the same block When it is desirable to turn straight-sided vessels the separations o-n the guide-rests F F are made straightsided, and the tool-bearers madeto move in horizontal lines.,

The chimes of the barrels are turned by means of a suitable tool, resting upon the The cross-headE is slotted, having crosspieces G passing through. By means of set-screws H the cross-pieces G are regulated, and with them the cross-head E is moved either to the right or to the left; and thus a corresponding position is imparted to the tool-bearer D.

By my improvement I am enabled to turn the bodies of barrels in one piece from the solid blocks, whereby I think I'can produce them cheaper, and in a superior manne'r, than they can be made from staves, and put together. There is no wasting of material, since by putting on a suihcientnumber of tool-bearers and cutters I can produce several barrels, `or tubs, one within another, each of a smaller size, at one operation. After the bodies of my barrels are thus turned, and the chimes cut, I fit in the heads, and then hoop them in the usual manner. For tight barrels, water-casks, tubs, kegs, and wooden vessels, of every description my improvement is peculiarly applicable.

I do not claim the making of the bodies of and feed-screws, I, in the manner and for barrels, casks, tubs, Snc., by turning them in the purposes, substantially, as described.
